WAVE-MOTOR.

SPECIFICATION forming part of Letters Patent No. 693,369, dated February 18, 1902. l

Application file'dJ'uly 20, 1900. Serial No. 24,294. (No model.)

To all whom t may concern- B e it known that I, WILLIAM S. BRYANT, of Cohasset, in the county of Norfolk and State of Massachusetts, have invented a new and useful Wave-Motor, of which the following is a specification.

My invention is a float connected with a platform by telescopicor like connections automatically actuating a pump to force Water and air into a reservoir.

The drawing isa central vertical section of the best form of my new Wave-motor.

'In the drawing, A is the float, (shown as a buoy,) and B a tube depending from the buoy. The reservoir D and the cylinder C of the pump are mounted in the -upper end of tube B, and the piston g of, the pump is counected to platform H'by means of the pistonrod g', spider h', and rods h. The platform H, rods h, spider h', and collar h2 constitute a cage, which telescopes upon the tube B of the buoy, being guided thereonby two collars b2, fixed to tube B, through which-the rods h pass and by the upper one of which the motion is limited. The substance o f the matter is that platform H and buoy A must have relative motion and that the 'two parts of the pump, which must also have relative motion, must be connected one to the buoy and the other to the platform, and suitable guides and stops are necessary as a practical matter to make the apparatus work properly and to enable it to stand the strains to which it is necessarily subjected, and all these details are of course capable of wide variation. f Cylinder C is provided with watery-inlet valves 97 and also with air-inlet valves g2 and with an outlet-valve g3 at one side of piston g, but preferably with only water-inlet valve g4 and Water-outlet valves g5 at the other side of the piston.

The outlet-valve g3 is shown as opening directly into reservoir D, while the outletvalves g5 are check-valves each in its pipe g,

which pipes open into reservoir D. The water-level rises in reservoir D until the air compressed in reservoir D above the waterlevel attains a pressure sufficient to force water mixed, of course, with some compressed air through pipe f, and this outflow from pipe f is utilized in any desired manner, one eX- ample being that described in my Patent No. 666,259, dated January 22, 1901.

The operation is as follows: In the best form of my apparatus the specific gravity of l y and a reservoir into which platform,l H and the parts carried by it is greater than that of Water, and consequently in still Water platform H will be at its maximum distance from buoy A instead of its minimum distance, as shown in the drawing; but this is not of very great importance, for if the specific gravity of the platform and its connections be less than that of Water then the drawing correctly shows the relative position of theplatformand buoy in still water; but as the buoy` is on the surface and the platform always well below the surface waves Will move the buoy relatively to the platform, and that relative motion willf actuate -the pump, and water and air will be forced into reservoir D, so that the water-level in reservoir D will rise rapidly, compressing air in reservoir D until the pressure is suiiicient t0 `force water mixed with compressed air through vpipe f against the resistancer caused by the work which is done by this'outflow through pipe f. The air which is absorbed and carried away by the waterescapiug from reservoir D is replaced by air from the pump, and thus the water in` reservoir D is always under air-pressure. l

I use the terms buoy and platform simplybecause in the best form of my apparatus the motions of a buoy are opposed by a platform `or drag; but of course I mean to include allopposed bodies which are moved relatively by Waves, provided their relative motion actuates a pump with 'au air-inlet as Well as a water-inlet and that pump supplies a reservoir with both Water and air.

Vhat I claim as my invention isi--V l.- The wave-motor above described made' u relatively movable by waves whose relative `motion actuateslthe pump.

2. In combination, a buoy; a tube depending from that buoy;` a platform; a ycagefextending from the platform and telescoping with the tube of thebuoy; a pump whose cylinder and piston are moved relatively by the relative motion of the buoy-and platform; the pump forces both water and air.

WILLIAM S. BRYANT.
